  • Abstract
  • Look Inside

A 52 years old man was admitted to our hospital because of dizziness and bradycardia. His ECG show-ed sinus bradycardia, sinus arrest and sinoatrial block associated with AV junctional escape beats. Right carotid sinus stimulation produced a 5.4 sec-ond ventricular asystole and decrease of systolic blood pressure of 45mmHg. The hyperactive caro-tid reflex by carotid sinus stimulation disappeared when 1mg of atropine was administered intrave-nously. These findings made convincingly the diag-nosis of cardioinhibitory type of carotid sinus syn-drome. He had a normal corrected sinus nodal recovery time (150ms) after atropine of 1mg. He was given cardioactive drug of orciprenaline sulfate, 60mg, and has been free of symptom.
